Hello,
I have been struggling for almost a month to solve the email problem.
It not receives but sent sends emails.
My hosting is on Contabo.
And I use CWP7pro as webpanel.
I will show pictures of what I see.

i use Cloudflare as DNS.
Routing is disabled in Cloudflare.
I need emails to work on [email protected].
The email sent messages to Gmail, but from Gmail to [email protected] it show error. It not even recevie email from [email protected] from [email protected]
From Gmail i got this:
Your message couldn't be delivered to [email protected] because the remote server is misconfigured. See technical details below for more information.
554 5.7.1 : Relay access denied

Please tell me what to change or what to add and where to do it.

Sorry for the question, I'm new to all this and it's very hard for me.
I would be very grateful if someone could help me solve the problem.

i use Cloudflare as DNS.

I find this case to be interesting. That's why I'd like to answer. According to pictures, the user's domain has a misconfigured MX record.

MX domain.com domain.com - DNS only

And the domain.com is proxied over CloudFlare. It would mean only ports TCP 80 and 443 are allowed. And emails would never reach the real server. In order to fix MX record should be changed. And it is actually changed already.

MX domain.com mail.domain.com - DNS only

And mail.domain.com should use DNS-only mode at CloudFlare.

p.s. CloudFlare format is used here for showing DNS records, it is not bind9)))
